摘　　要：针对数据采样以及同步传输的方式,提出了基于可编程逻辑器件FPGA(现场可编程逻辑陈列)和USB 2.0(通用串行总伐2.0)芯片为核心的同步数据传输系统。该方法通过在FPGA内部设计集成了增强型8051微处理器和接口逻辑,利用软硬件协同工作方式实现系统控制,从而完成对外部数据的采集以及同步传输至上位机。经过理论分析、逻辑仿真和实际电路验证表明,所设计的数据传输系统较传统数据传输方法在传输速率以及灵活性上得到显著的提升。As for the method of data acquisition and synchronization, the paper raises the system of data transmission base on FPGA and USB2.0. In the FPGA, the system integrates the 8051 core and interface logical. The system completes the data acquisition and transmission by the cooperation work between hardware and software. By the analysis of theory, logic simulation and verification of the circuit, the design has a good improvement on transmission rate and flexibility which compared to the traditional method.
